Using FloraNova Grow for potted trees

[Daintree]

Hi All,
Does anybody use General Hydroponics FloraNova on their potted plants???

I use it in my aeroponics tower and LOVE it.  It says you can use it for potted plants also.  The GH rep said to only use it four times a year.  The thing that appeals to me about it is that it has all the major, minor and micro nutrients in a liquid formula.
It is fairly expensive, but seems worth it for the convenience.

I am so tired of mixing, dissolving, waiting, shaking, waiting, dissolving, shaking, ad nauseum...

Thanks!
Carolyn
